激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?generally single crystals (monocrystalline optical resources) �?which can be made use of as obtain media for good-condition lasers. Most often, They may be doped with both trivalent uncommon earth ions or changeover metallic ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping concentration from the obtain medium are most advantageous rely upon various components. The readily available pump supply (form of laser diode or lamp) along with the envisaged pumping arrangement are essential aspects, but the material by itself also has some influence. For example, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is more ideal than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
g. a skinny disk. As One more case in point, Q-switched lasers get to the next population density from the higher laser level and so are consequently a lot more delicate to quenching outcomes and Electrical power transfer processes; consequently, a decrease doping density is commonly suitable for these equipment. For top-energy lasers, reduced doping densities in click here many cases are accustomed to Restrict the density of heat era, Though thin-disk lasers function greatest with very doped crystals. Several laser items usually do not reach the comprehensive performance opportunity mainly because these specifics have not been adequately worked out.
The host crystal is much more than just a way to repair the laser-Lively ions at specific positions in Place. A number of Qualities on the host material are important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is clear that unique apps bring on very various specifications on laser obtain media. For that reason, a wide vary of different crystals are employed, and building the appropriate decision is essential for developing lasers with optimum performance.

The medium should have a superior transparency (very low absorption and scattering) while in the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on details with the fabrication procedure.
Applying our promoting package, you may Display screen your logo, even further below your merchandise description, and these will been seen by several photonics gurus.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
